Imboni yamakhemikhali kaphethiloli imi njengomgogodla wokukhiqiza emhlabeni jikelele, okuhlanganisa ukukhiqizwa, ukuhluzwa, kanye nokuthuthwa kukawoyela ongahluziwe, igesi yemvelo, kanye nemikhiqizo ehlukahlukene etholakala kwamanye amazwe. Kulo mkhakha obaluleke kakhulu, lapho imisebenzi ihilela khona uketshezi oluyingozi, ukucindezela okuphezulu, amazinga okushisa aphezulu, kanye nezidingo zomthetho eziqinile, ukulinganisa uketshezi okunembile nokuthembekile akuyona nje indaba yokusebenza kahle—kuyisivikelo esibalulekile sokuphepha, ukuhambisana, kanye nenzuzo. Phakathi kobuchwepheshe obuhlukahlukene bokulinganisa ukugeleza obutholakalayo, amamitha okugeleza ngobuningi (ama-MFM) avele njengendinganiso yegolide yezicelo zamakhemikhali kaphethiloli, eletha ukunemba nokuphepha okungenakuqhathaniswa okuhambisana nezidingo eziqinile zemboni.
Ngokungafani namamitha okugeleza evolumu, alinganisa umthamo woketshezi oludlula epayipini, amamitha okugeleza esisindo alinganisa ngqo izinga lokugeleza kwesisindo soketshezi—ikhono elibalulekile embonini yamakhemikhali kaphethiloli. Uwoyela ongahluziwe, amafutha acwengisiwe, kanye namakhemikhali aphakathi avame ukubonisa ubuningi obuguquguqukayo ngenxa yezinguquko ekushiseni, ingcindezi, kanye nokwakheka. Ukulinganiswa kwevolumu, okuzwela kulezi ziguquguquko, kungaholela ekunganeni okukhulu, okuholela ekulahlekelweni kwezezimali (isb., ekuhwebeni komkhiqizo) noma ezingozini zokusebenza (isb., ukugcwaliswa ngokweqile kwamatangi okugcina). Amamitha okugeleza esisindo, ngokuphambene, ahlinzeka ngokufundwa kwesisindo okuqondile okungathinteki ukushintshashintsha kobuningi, okuqinisekisa ukunemba okuqhubekayo kuzo zonke izimo zokusebenza ezahlukahlukene ezivamile zezinqubo zamakhemikhali kaphethiloli.
Ukuphepha kuyinto ebaluleke kakhulu ekusebenzeni kwe-petrochemical, lapho ukuvuza noma ukulinganisa kabi uketshezi oluvuthayo, olunobuthi, noma oluqothulayo kungaholela ezingozini ezinkulu, ekungcolisweni kwemvelo, kanye nokulahlekelwa yimpilo. Amamitha okugeleza ngobuningi aklanyelwe ukunciphisa lezi zingozi ngokuklama okuqinile kanye nezici zokuphepha ezithuthukisiwe. Amamitha okugeleza ngobuningi be-Coriolis, uhlobo olusetshenziswa kakhulu ekusetshenzisweni kwe-petrochemical, anomklamo ovalwe, ongaphazamisi ongenazo izingxenye ezihambayo emfudlaneni woketshezi. Lokhu kususa ingozi yokwehluleka kwemishini noma ukuguguleka okungabangela ukuvuza, okwenza kube kuhle kakhulu ukuphatha uketshezi oluyingozi njengowoyela ongahluziwe, i-benzene, ne-ethylene. Ngaphezu kwalokho, amamitha amaningi okugeleza ngobuningi bezinga lezimboni akhiwe ngezinto ezingamelani nokugqwala—njengensimbi engagqwali, i-Hastelloy, noma i-titanium—ezingamelana nohlobo olunamandla loketshezi lwe-petrochemical, okuthuthukisa ukuphepha kokusebenza futhi kwandise isikhathi sokuphila kwemishini.
Ukunemba kwamamitha okugeleza kobuningi kubaluleke kakhulu ekuhlanzweni kwe-petrochemical kanye nokusatshalaliswa komkhiqizo, lapho ngisho nokuphambuka okuncane kokulinganisa kungaholela emiphumeleni emikhulu yezezimali. Isibonelo, ekuhlanzweni kwe-oyili engahluziwe, ukulinganiswa okunembile kokugeleza kobuningi bezinto zokudla kuqinisekisa ukulawulwa kwenqubo okuhle kakhulu, kukhulisa isivuno semikhiqizo enenani eliphezulu (isb. uphethiloli, udizili) ngenkathi kunciphisa imfucuza. Ekuhwebeni komkhiqizo, lapho izimpahla zithengwa futhi zithengiswa ngokusekelwe kubuningi, ukufundwa okunembile kwe-MFM kuqinisekisa ukuthengiselana okufanele futhi kuvimbele ukulahlekelwa kwemali engenayo. Amamitha okugeleza kobuningi besimanje anikeza ukunemba okungavamile - ngokuvamile ngaphakathi kwe-±0.1% yenani elilinganisiwe - enza kahle kakhulu kunobuchwepheshe bokulinganisa ukugeleza kwendabuko futhi ahlangabezane nezidingo eziqinile ze-metrological zemboni ye-petrochemical kanye nezinhlangano ezilawulayo njenge-American Petroleum Institute (API) kanye ne-International Organization for Standardization (ISO).
Izinqubo ze-Petrochemical zisebenza kuzo zonke izimo ezimbi kakhulu, kusukela kumapayipi kawoyela ongahluziwe anomfutho ophezulu (adlula amabha ayi-100) kuya kumayunithi okuhlanza anokushisa okuphezulu (afinyelela ku-400°C) kanye nezindawo zokugcina igesi yemvelo encibilikisiwe (i-LNG) enokushisa okuphansi (-162°C). Amamitha okugeleza kobuningi aklanyelwe ukuchuma kulezi zindawo ezinzima, ngamakhono okunciphisa izinga lokushisa nokucindezela athuthukisiwe aqinisekisa ukufundwa okunembile ngisho noma izimo zokusebenza zishintshashintsha. Isibonelo, amamitha okugeleza kobuningi be-Coriolis asebenzisa izinzwa ezakhelwe ngaphakathi ukuqapha izinga lokushisa koketshezi nokucindezela ngesikhathi sangempela, ukulungisa izilinganiso ngokuzenzakalelayo ukuze kubhekelwe noma yiziphi izinguquko. Lokhu kuvumelana nezimo kuwenza afanelekele uhla oluhlukahlukene lwezicelo ze-petrochemical, okuhlanganisa ukukhipha uwoyela ongahluziwe, ukucubungula igesi yemvelo, ukukhiqizwa kwe-polymer, kanye nokuxubana kwamakhemikhali.
Ngaphezu kokuphepha nokunemba, amamitha okugeleza kobuningi anegalelo ekuthuthukisweni kokusebenza kahle kanye nokuguqulwa kwedijithali embonini yamakhemikhali kaphethiloli. Ama-MFM anamuhla afakwe izixhumi zokuxhumana zedijithali—njenge-RS485, i-Modbus, noma i-Foundation Fieldbus—ezivumela ukuhlanganiswa okungenamthungo nezinhlelo zokulawula inqubo (PCS) kanye nesofthiwe yokuhlela izinsiza zebhizinisi (ERP). Lokhu kuvumela ukuqapha izinga lokugeleza kwesikhathi sangempela, ukufinyelela idatha ekude, kanye nokulungiswa kwenqubo okuzenzakalelayo, okunika amandla opharetha ukwenza ngcono izinqubo zokukhiqiza, ukunciphisa ukusetshenziswa kwamandla, kanye nokubikezela izidingo zokulungisa. Isibonelo, ngokuqapha izinga lokugeleza kobuningi bezinto ezibangela ukungcola enkambisweni ye-polymerization, opharetha bangalungisa imithamo ukuze bathuthukise ikhwalithi yomkhiqizo futhi banciphise ukungcola kwezinto. Izexwayiso zokulungisa ezibikezelayo, ezisekelwe kudatha evela kuzinzwa ze-MFM, nazo zisiza ukunciphisa isikhathi sokungasebenzi esingahleliwe—inzuzo ebalulekile embonini lapho ukuphazamiseka kokukhiqiza kungabangela ukulahlekelwa yizigidi zamaRandi.
Uma ukhetha imitha yokugeleza kwesisindo sezicelo ze-petrochemical, izici eziningana ezibalulekile kumele zicatshangelwe ukuqinisekisa ukusebenza kahle. Okokuqala, imitha kumele ihambisane nezakhiwo ezithile zoketshezi, okuhlanganisa i-viscosity, ukugqwala, kanye nokwakheka kwamakhemikhali. Okwesibili, kumele ihlangabezane nezidingo zokucindezela kokusebenza kanye nokushisa kwesicelo. Okwesithathu, ukunemba kwemitha kanye nesilinganiso sokujika (ububanzi bamazinga okugeleza engayilinganisa ngokunembile) kumele kuhambisane nezidingo zenqubo. Okokugcina, ukuhambisana nezindinganiso zemboni kanye nezitifiketi—njenge-ATEX yezindawo eziqhumayo noma i-NACE yokumelana nokugqwala—kubalulekile ukuqinisekisa ukuphepha kanye nokuhambisana nemithetho.
Ekuphetheni, amamitha okugeleza kobuningi abe ngamathuluzi abalulekile embonini yamakhemikhali kaphethiloli, eletha ukuphepha, ukunemba, kanye nokuthembeka okudingekayo ukuze kuhlangatshezwane nezinselele ezihlukile zomkhakha. Amandla abo okuhlinzeka ngezilinganiso eziqondile zokugeleza kobuningi, ukumelana nezimo zokusebenza ezimbi kakhulu, kanye nokuhlanganiswa nezinhlelo zokulawula zedijithali kubenza babe yingxenye ebalulekile yokusebenza kwesimanje kwamakhemikhali kaphethiloli. Ngokuqinisekisa ukulinganiswa koketshezi okunembile, amamitha okugeleza kobuningi asiza izinkampani zamakhemikhali kaphethiloli ukuthuthukisa ukuphepha, ukuthuthukisa ukusebenza kahle, ukugcina ukuthobela imithetho, kanye nokuvikela inzuzo. Njengoba imboni yamakhemikhali kaphethiloli iqhubeka nokuthuthuka ekushintsheni kwedijithali kanye nokusimama okukhulu, amamitha okugeleza kobuningi azohlala ehamba phambili kwezobuchwepheshe bokulinganisa, okwenza kube nokusebenza okuphephile, okusebenzayo, nokusimeme kakhudlwana. Kwabasebenzi bamakhemikhali kaphethiloli, ukutshala imali kumamitha okugeleza kobuningi asezingeni eliphezulu akuyona nje isinqumo sobuchwepheshe - kuwukutshalwa kwezimali okunesu empumelelweni yesikhathi eside kanye nokuqina kwemisebenzi yabo.
